ABSTRACT:
A drive apparatus includes a pair of axial piston pump assemblies in an inline relationship, each pump assembly having an end cap mounted to a pump housing to form a sump. The pump assemblies are mounted to a gearbox at one end thereof, and an input shaft extends into both pump housings and the gearbox to drive the axial piston pumps and one of the gears. A power take off mechanism is also engaged to the gearbox at another end thereof and includes a drive shaft at least partially disposed in the gearbox and driven by one of the transmission gears, and an output shaft extending in the opposite direction from the drive shaft.
